Re: Analog_Bridge gain


Dennis Ramos
 

hello guys, i just wonder if you can help me to increase my dmr audio going to allstarlink. it is a little bit low.

my existing setting are this; default

[USRP]
server = 127.0.0.1                      ; IP address of Allstar/Asterisk
toASLPort = 32001                       ; Analog_Bridge <-- ASL
fromASLPort = 34001                     ; Analog_Bridge --> ASL
aslAudio = AUDIO_UNITY                  ; Audio to ASL (AUDIO_UNITY, AUDIO_USE_AGC, AUDIO_USE_GAIN)
agcGain = -20                           ; Gain (in db) of the AGC filter
dmrAudio = AUDIO_UNITY                  ; Audio from ASL (AUDIO_UNITY, AUDIO_USE_GAIN, AUDIO_BPF)
dmrGain = 0.35                          ; Gain factor of audio from ASL (0.0-1.0)


actually i would like to understand those unity, use agc and use gain setting, and the gain levels in db. what are those for.

many thanks in advance
